Summary This is the absolute-best multi-tester for non-diamond / diamond / Moissanite this is best tester for the new (low-conductivity) Moissanites that show up as 'diamond' on most testers fastest response time (test-result in 1 second) left-handed or right-handed use thinnest probe (0.45mm) tests stones as small as 0.01 carat (1 point) can be used with batteries (included) or USB power (cable not included) in its case it's smaller an neater than other diamond testers. one year guarantee See our Guide to buying diamond testers. Guarantee: 1 year. Operation Turn it on, wait 10 seconds for it to warm up, place the probe in the centre of the stone, large clear LED bars indicate: Low Batt, Metal alert (meaning you've missed the stone and touched the setting), Simulant (i.e. not diamond), Moissanite,, Diamond, Touched metal (i.e. you missed the stone and tested the setting). Technical Size 170mm (6.69 inches) X 31mm (1.2 inches) X 28mm (1.1 inches) Weight 55g (1.94 oz) Tests stones from 0.01 to 10 carats incl. mounted stones in any setting Operating temperature 18 to 27 degrees C (64 to 81 degrees F) RESPONSE TIME Start-up time 10 seconds Testing time 1 second Warm-up time between tests 2 seconds POWER Power: three AAA batteries (supplied) or any USB power source (USB cable not supplied). NOTE: the USB cable is to power the tester directly, it does not charge batteries. Also, IF you use rechargeable batteries they must be lithium, not the standard NiMH. Battery life: 2000 continuous tests with good quality alkaline batteries, eg Duracell  Auto-power-off yes, if used on battery power it turns itself off after 10mns with no activity. Low battery indicator: yes ACCESSORIES / PRESENTATION Neat heavy-duty carrying pouch Summary of instructions (you are meant to download the full instruction booklet). LIMITATIONS Will not test fancy-coloured stones; no 'low batt' indicator;  synthetic diamonds (not to be confused with simulants!) usually register as Moissanite; the Moissanite test is very sensitive, both stone and test-tip must be 100% clean and grease-free, you will cover the stone in a layer of grease simply by touching it with your finger (this is a 'limitation' for anyone expecting a quick-easy-accurate test).   Video (lasts 1mn) Disclaimer All testers must be used in conjunction with the user's skill, knowledge and experience. Under no circumstances shall QUICKTEST be liable for direct or indirect loss sustained in connection with any item. Nothing is 100% accurate, you must understand the limitations of any tester. We also suggest you regularly test known samples to check for any obvious faults.  Please note, none of these testers will distinguish natural stones from synthetic stones. "Synthetic" is a scientific term meaning 'made by man in a factory/laboratory to the same formula found in nature'. The two are usually indistinguishable, synthetic diamond is diamond (read about synthetic diamond testers and see our ARI and ARETE models). The testers below are to distinguish diamond from non-diamond (simulant/imitation).    Model Tests mounted stones [1] Tests  Diamond Tests  Moissanite Tests Ruby /  Sapphire Other stones Diamond selector II, (DT-DS-crp) (works some of the time) ✔ ✔ Shows up as diamond ✘ No reaction on non-diamond Diamond selector II  (DT-DS) (cheap but works most of the time) ✔ ✔ Shows up as diamond ✘   No reaction on non-diamond Diamond Experior (best diamond-only tester) ✔ ✔ Shows up as diamond ✘ Non-diamond reads 'Other Stone' Moissanite tester by GemVue (Moissanite Plus) MOISS-4) ✔ ✘ ✔ ✘ You must only test stones you are certain are diamond Multi tester.
